In JavaScript can I make a “click” event fire prog

Question

I'd like to make a click event fire on an <input type="file"> tag programmatically.

Just calling click() doesn't seem to do anything or at least it doesn't pop up a file selection dialog.

I've been experimenting with capturing events using listeners and redirecting the event, but I haven't been able to get that to actually perform the event like someone clicked on it.

Answer 1

just use a label tag, that way you can hide the input, and make it work through its related label https://developer.mozilla.org/fr/docs/Web/HTML/Element/Label

Answer 2

This will now be possible in Firefox 4, with the caveat that it counts as a pop-up window and will therefore be blocked whenever a pop-up window would have been.

Answer 3

Here is solution that work for me: CSS:

#uploadtruefield {
    left: 225px;
    opacity: 0;
    position: absolute;
    right: 0;
    top: 266px;
    opacity:0;
    -moz-opacity:0;
    filter:alpha(opacity:0);
    width: 270px;
    z-index: 2;
}

.uploadmask {
    background:url(../img/browse.gif) no-repeat 100% 50%;
}
#uploadmaskfield{
    width:132px;
}

HTML with "small" JQuery help:

<div class="uploadmask">
    <input id="uploadmaskfield" type="text" name="uploadmaskfield">
</div>
<input id="uploadtruefield"  type="file" onchange="$('#uploadmaskfield').val(this.value)" >

Just be sure that maskfied is covered compeltly by true upload field.

Answer 4

I found that if input(file) is outside form, then firing click event invokes file dialog.
